Kind of comparing apples and oranges in this one aren't you. Bravery has nothing to do with proposed senerio. I would say more it''s smart of dumb. You prepare for possible problems, that's smart. Not preparing is stupid. so it's not brave or foolish, it's stupid or smart.[8D]
That makes sense. Brave would be going hunting for grizzly without a back up firearms shooter but being successful. Foolish would be doing the same but being eatin by the bear.
